Bently Nevada 330930-060-02-CN NSv Cable 6m

Bently Nevada 330930-060-02-CN 3300 NSv Extension Cable

Product Introduction

This Bently Nevada 330930-060-02-CN belongs to the 3300 NSv series and functions as a precision extension cable for proximity measurement systems. It establishes a reliable connection between the 3300 NSv probe and the Proximitor Sensor. Additionally, this model includes stainless steel armor without an FEP outer jacket, offering robust mechanical protection in a lighter configuration. The cable measures exactly 6.0 meters (19.7 feet) in length, providing extended reach for various installation requirements. High-quality 75Ω coaxial construction ensures consistent signal integrity throughout its service life. This version carries country-specific CN approvals, making it suitable for installations requiring Chinese regulatory compliance.

Key Technical Specifications

The Bently Nevada 330930-060-02-CN delivers precise electrical performance for accurate system measurements. Its typical extension cable capacitance measures 69.9 pF/m (21.3 pF/ft) . The center conductor DC resistance registers at 0.220 Ω/m (0.067 Ω/ft) , while the shield resistance reads 0.066 Ω/m (0.020 Ω/ft) . These electrical parameters guarantee consistent operation within the 3300 NSv system architecture. Moreover, the cable utilizes a 75 Ω coaxial, fluoroethylene propylene (FEP) insulated construction. This insulation material offers excellent dielectric strength and resists chemical attack effectively. Gold-plated brass connectors provide superior corrosion resistance and maintain reliable signal contact over time.

Mechanical and Environmental Ratings

This armored extension cable withstands severe operating conditions with ease. The flexible armor consists of AISI 302 stainless steel without an FEP outer jacket, delivering mechanical protection while reducing overall weight. Its operating and storage temperature range extends from -51°C to +177°C (-60°F to +351°F) . The cable weighs approximately 1.5 kg in total for the 6.0-meter length. The tensile strength rating reaches 220 N (50 pounds) at all critical connection points, including the probe case to probe lead, probe lead to extension cable connectors, and probe case to stainless steel armor. This robust construction ensures reliable performance in demanding industrial environments.

Agency Approvals and Compliance

The 330930-060-02-CN distinguishes itself through its country-specific CN approval option. This designation indicates compliance with Chinese regulatory requirements for industrial equipment. The CN Approvals Option Quick Reference Guide and Field Notification Letter are available in the download section for your reference. These documents provide detailed information about the specific certifications and compliance standards this cable meets. For installations within China or projects requiring Chinese regulatory approval, this cable version offers the necessary documentation and certification. Furthermore, this approval simplifies the procurement process for facilities operating under Chinese regulatory frameworks.

System Compatibility and Integration

This 330930-060-02-CN cable integrates smoothly into the complete 3300 NSv monitoring ecosystem. When selecting system components, ensure that the extension cable length and probe length add together to equal the Proximitor Sensor total length. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) conductors, with a maximum permissible length of 305 meters (1,000 feet) between the 3300 XL NSv Proximitor Sensor and the monitor. Specifically, the linear range spans 1.5 mm (60 mils) , starting at approximately 0.25 mm (10 mils) from the target surface. The recommended gap setting is 1.0 mm (40 mils) . The NSv system offers higher sensitivity compared to standard 3300 XL systems, making it ideal for applications requiring finer measurement resolution.

Installation Guidelines

Installing the Bently Nevada 330930-060-02-CN follows a straightforward process when you adhere to standard procedures. First, clean the cable connectors thoroughly and check for debris before mating them with the probe and Proximitor Sensor. Next, route the cable along a path that avoids sharp bends or excessive pulling force, as these conditions could damage the armor or internal conductors. Ensure that the total system length matches the Proximitor Sensor's specified requirements by adding the probe length and extension cable length correctly. Furthermore, the 3300 NSv probe comes with appropriate mounting hardware for secure installation. Finally, tighten all connections to the specified torque values to preserve system integrity. For humid or moist environments, we recommend using connector protectors for additional sealing.

Frequently Asked Questions

1. What does the CN approval option mean for this extension cable?

The CN approval option indicates that this cable meets country-specific Chinese regulatory requirements. The Quick Reference Guide and Field Notification Letter provide detailed compliance information and are available in the download section.

2. What is the difference between this cable and the version with an FEP jacket?

This cable features stainless steel armor without an FEP outer jacket, making it slightly lighter than the jacketed version. Both options provide mechanical protection, though the FEP jacket offers additional chemical and moisture resistance.

3. What is the exact length of the Bently Nevada 330930-060-02-CN cable?

This cable has a fixed length of 6.0 meters, which equals approximately 19.7 feet. It belongs to the 3300 NSv system and does not allow field shortening or extension.

4. How do I ensure proper total system length with this extension cable?

Add the extension cable length and the probe length together to equal the Proximitor Sensor total length. For example, a 6.0-meter extension cable requires a probe length that completes the system length specified by your Proximitor Sensor.

5. What are the tensile strength ratings for this extension cable?

The tensile strength rating reaches 220 N (50 pounds) at all connection points, including the probe case to probe lead, probe lead to extension cable connectors, and probe case to stainless steel armor.
